在使用openstack4j连接调用OpenStack时,报错

具体部分报错:

Exception in thread "main" ConnectionException{message=RESTEASY004655: Unable to invoke request, status=0}
    at org.openstack4j.connectors.resteasy.HttpExecutorServiceImpl.invoke(HttpExecutorServiceImpl.java:57)

OpenStack环境:通过在两台虚拟机上搭建的OpenStack环境,两台虚拟机的主机名分别为controller、compute。而这里报错为未知主机。

解决:

(1)在Windows下打开windws/system32/driver/etc/hosts,添加以下内容

        虚拟机IP controller
        虚拟机IP compute

(2)linux服务器

vi  /etc/hosts
